I got curious and looked at a few film files to see what format they use.  Much of the header format is pretty obvious, as are the "talk blocks".  Dunno if this is useful to anyone, but here it is.  If you have more to add to it, please do.

Note that in random-teams games, the composition of the teams is not stored in the film file, as far as I can tell.  Probably there is a random number seed stored in the header somewhere, and the teams get formed "randomly" in playback in the same manner that they were formed when the game was played.  So without knowing where the random number seed is stored, and more importantly knowing Myth's procedure for creating random teams, there's no way to determine what the random teams are simply by examining a film file.

Talk blocks are in this format:
	09 == this is a "talk"
        player number (0-based)
	four bytes timestamp == 30ths of seconds elapsed
	00 01 == ?
	ASCII message
